The TOM-1 can add two numbers together to get 0x10 (seen in the lower left red LED strip). The 16-pin grey ribbon cable connects to the ALU on the right (breadboards #7 and #8). I'm debating the best strategy to wire circuits together, going back and forth between ribbon cables and repositioning chips to allow better direct wiring.
